Abstract
We investigate the regulation of labor markets through employment, collective relations,
and social security laws in 85 countries. We find that the political power of the left is associated
with more stringent labor regulations and more generous social security systems, and that
socialist, French, and Scandinavian legal origin countries have sharply higher levels of labor
regulation than do common law countries. However, the effects of legal origins are larger, and
explain more of the variation in regulations, than those of politics. Heavier regulation of labor is
associated with lower labor force participation and higher unemployment, especially of the
young. These results are most naturally consistent with legal theories, according to whichcountries have pervasive regulatory styles inherited from the transplantation of legal systems.

I. Introduction
Every country in the world has established a complex system of laws and institutions
intended to protect the interests of workers and to help assure a minimum standard of living for
its population. In most countries, in addition to some basic civil rights protections, this system
encompasses three bodies of law: employment law, collective relations law, and social security
law. Employment laws govern the individual employment contract. Collective or industrial
relations laws regulate the bargaining, adoption, and enforcement of collective agreements, the
organization of trade unions, and the industrial action by workers and employers. Social security
laws govern the social response to needs and conditions that have a significant impact on the
quality of life, such as old age, disability, death, sickness, and unemployment.
In this paper, we examine these laws in 85 countries through the lens of three major
theories of institutional choice: the efficiency theory, the political power theory, and the legal
theory. The efficiency theory holds that institutions adjust to serve the needs of a society most
efficiently. Each society chooses a system of social control of business that optimally combines
market forces, dispute resolution in court, government regulation, and corrective taxes and
subsidies [Djankov et al. 2003a]. Under the political power theory, institutions are shaped by
those in power to benefit themselves at the expense of those out of power. Both voting and
interest group politics allow the winners to benefit at the expense of the losers, with checks and
balances on the government limiting the extent of redistribution. Under the legal theory, a
country’s approach to regulation is shaped by its legal tradition. Most countries in the world
have inherited their basic legal structures from their colonizers, such as the English, the French,
the Germans, the Portuguese, or the Spanish, or their conquerors, such as Napoleon or the
Soviets. The laws of the different colonizers and occupiers belong to different legal traditions,
which significantly influenced the legal systems of conquered countries [Zweigert and Kotz
1998, La Porta et al. 1997, 1998]. In broad terms, common and civil law traditions utilize
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 3/453
different strategies for dealing with market failure: the former relying on contract and private
litigation, the latter on direct supervision of markets by the government. Under this theory, the
historical origin of a country’s laws shapits regulation of labor and other markets.1
Our focus on labor laws might be particularly helpful in distinguishing political power
and legal theories. Roe [2000] and Pagano and Volpin [2001] argue that the political power of
labor has been central to legal and regulatory design of the twentieth century. Using data on
OECD countries, these authors challenge the observation of La Porta et al. [1997, 1998] that the
differences in financial development among common and civil law countries are best understood
in terms of legal theories. Roe [2000] maintains that civil law is simply a proxy for social
democracy. An analysis of labor laws gives these political theories their best shot, for two
reasons. First, we expect leftist governments to regulate labor markets to benefit their
supporters. Second, because labor laws are relatively recent, we would not expect a profound
influence of legal tradition on their structure.
To assess these theories, we collect data on employment, collective relations, and social
security laws as of 1997 for the Djankov et al. [2002] sample of 85 countries, and code them to
measure worker protection. We combine these data with existing (and some newly collected)
information on economic development, leftist orientation of governments, union power, political
constraints on government action, and legal origins to examine the determinants of the regulation
of labor. We also examine data on the unofficial economy, labor force participation,
unemployment, and relative wages to consider who benefits and who loses from the regulation of
labor.
The available research on labor regulations is more extensive than that on most other
laws. The Organization of Economic Cooperation and Development has sponsored the creation
of a database of labor regulations in member countries [Nicoletti, Scarpetta, and Boylaud 1999,
1. In footnotes, we also consider the cultural theory, under which regulations are shaped by a country’s
cultural history, such as the dominance of particular religious groups. The data do not support this theory, so we
keep its discussion to a minimum.

Nicoletti and Pryor 2001]. The World Bank has assembled a data base of International Labor
Office certifications for 119 countries, which provide a partial view of the labor laws as well
[Forteza and Rama 2000]. Heckman and Pages-Serra [2000] examine an extensive data set of
job security regulation for Latin American and Carribean countries. Mulligan and Sala-i-Martin
[2004] assemble and analyze data on social security systems. What distinguishes our data from
previous efforts is a combination of a significant coverage of countries and a comprehensive
approach to labor market regulations.2
In the next section, we briefly describe the theories of the determinants of labor
regulations. In section III, we describe the data. In section IV, we illustrate the data by
comparing New Zealand and Portugal. In section V, we examine the determinants of labor
market regulations. In section VI, we compare patterns of labor regulation to those of other
activities. In section VII, we look at the consequences of regulation. Section VIII concludes.
II. Hypotheses
II.A. Background
Why do governments intervene in the labor market? The theory underlying most
interventions is that free labor markets are imperfect, that as a consequence there are rents in the
employment relationship, and that employers abuse workers to extract these rents, leading to
both unfairness and inefficiency. For example, employers discriminate against disadvantaged
groups, underpay workers who are immobile or invest in firm-specific capital, fire workers who
then need to be supported by the state, force employees to work more than they wish under the
threat of dismissal, fail to insure workers against the risk of death, illness or disability, and so on.
In response to the perceived unfairness and inefficiency of the free market employment
relationship, nearly every state intervenes in this relationship to protect the workers.
2. There is also an extensive literature on the consequences of regulation of labor, including Lazear
[1990], Besley and Burgess [2003], Fonseca, Lopez-Garcia, and Pissarides [2000], Heckman and Pages-Serra
[2000], and Ichniowski, Freeman, and Lauer [1989].
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 5/455
Regulation of labor markets aiming to protect workers from employers takes four forms.
First, governments forbid discrimination in the labor market and endow the workers with some
“basic rights” in the on-going employment relationships, such as maternity leaves or the
minimum wage. Second, governments regulate employment relationships, by for example
restricting the range of feasible contracts and raising the costs of both laying off workers and
increasing hours of work. Third, in response to the power of employers against workers,
governments empower labor unions to represent workers collectively, and protect particular
union strategies in negotiations with employers. Finally, governments themselves provide
social insurance against unemployment, old age, disability, sickness and health, or death. The
basic question addressed in this paper is what determines these choices of government
intervention in the labor market? We consider three broad theories along these lines.
II.B. Efficiency
Demsetz [1967] and North [1981] propose that the choice of institutions is dictated
primarily by efficiency considerations. In the present context, this approach broadly implies that
countries choose a combination of labor market interventions to maximize social welfare. The
standard interpretation of this objective is curing market failures. More recent research has
focused on identifying public interventions that are themselves cheapest and least vulnerable to
subversion [Glaeser and Shleifer 2002, 2003, Glaeser, Scheinkman, and Shleifer 2003, Djankov
et al. 2003b]. For example, countries would choose heavier intervention when employer abuse
of employees in the market is greater (to cure market failures), and lighter intervention when
distortions associated with government interference are more severe (to cut social enforcement
costs).
By itself, the efficiency theory is too broad to have strong implications for the extent and
consequences of regulation, and as such is difficult to reject. We examine two of its plausible,
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 6/456
but not unambiguous, implications. First, if government intervention in the labor market in the
form of worker protection is efficient, then it should not have large adverse consequences, such
as unemployment, withdrawal of people from the labor force, and the growth of the unofficial
economy. Of course, it is possible that the benefits of regulation to protected workers are higher
than these distortions, making the overall welfare assessment indeterminate. Second, if
efficiency is the correct model, political factors such as the power of the left or constraints on
government would not shape regulatory choices. Again it is possible that some divided societies
efficiently require more regulations to preserve social peace, and efficiently pick leftist
governments to enact them. We show, however, that if anything divided societies regulate less
(see footnote 14). The relationship between efficiency and legal theories is even more complex,
and we discuss it below.
II.C. Political Power
According to political power theories, institutions are designed to transfer resources from
those out of political power to those in power, as well as to entrench those in political power at
the helm [Marx 1872, Olson 1993, Finer 1997]. In the context of labor markets, these theories
imply that labor regulations are more protective of workers when leftist governments are in
power. Such protection can restore efficiency if in a free market workers are “abused,” or in
lower efficiency if government intervention leads to expropriation of capital by labor.
Political power theories come in two varieties. The first holds that the principal mode of
political decision making is elections, and that the parties that win them shape laws. The second
variety, which applies to both democracies and dictatorships, holds that laws are shaped by the
influence of interest groups [Olson 1965, Stigler 1971, Posner 1974, Becker 1983].
Political power theories are by far the leading explanation of the choice of labor
regulations. In the electoral version, they hold that regulations protecting workers (or at least
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 7/457
employed workers) are introduced by socialist, social-democratic, and more generally leftist
governments to benefit their political constituencies [Esping-Andersen 1990, 1999, Hicks 1999].
In the interest group version, these theories hold that labor regulations respond to the pressure
from trade unions, and should therefore be more extensive when the unions are more powerful,
regardless of which government is in charge.
Political theories also hold that the ability of those in power to use regulations to benefit
themselves is limited by checks and balances on the government [Buchanan and Tullock 1962].
Dictatorships are less constrained than democratically elected governments, and therefore will
have more redistributive laws and institutions. Constitutions, legislative constraints, and other
forms of checks and balances are all conducive to fewer regulations. This theory found some
empirical support in our previous work on the regulation of entry [Djankov et al. 2002].
II.D. Legal Theory
Legal theory has received considerable attention in the discussions of institutional
evolution. This theory emphasizes the emergence of two very distinct legal traditions in Western
Europe as far back as the 12th
century, namely common law and civil law, and the transplantation
of these traditions both within Europe and to the new world through conquest and colonization.
Importantly, because most countries in the world received their basic legal structures in this
involuntary way, these structures are exogenous to their economies.
Common law emerged in England and is characterized by the importance of decision
making by juries, independent judges, and the emphasis on judicial discretion as opposed to
codes. From England, common law was transplanted to its colonies, including Ireland, U.S.,
Canada, Australia, New Zealand, India, Pakistan and other countries in South and East Asia,
East Africa and the Caribbean.
Civil law evolved from Roman law in Western Europe through the middle ages, and was
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 8/458
incorporated into civil codes in France and Germany in the 19th
century. Civil law is
characterized by less independent judiciaries, the relative unimportance of juries, and a greater
role of both substantive and procedural codes as opposed to judicial discretion. Through
Napoleonic conquest French civil law was transplanted throughout Western Europe, including
Spain, Portugal, Italy, Belgium, and Holland, and subsequently to the colonies in North and
West Africa, all of Latin America, and parts of Asia.
In addition to common law and French civil law, three legal traditions play some role in
parts of the world. The German code became accepted in Germanic Western Europe, but also
was transplanted to Japan and from there to Korea, and Taiwan. Socialist law was adopted in
countries that came under the influence of U.S.S.R.. Finally, an indigenous Nordic or
Scandinavian legal tradition developed in Sweden, Norway, Denmark, and Finland.
The legal theory holds that countries in different legal traditions utilize different
institutional technologies for social control of business [Djankov et al. 2003b]. Common law
countries tend to rely more on markets and contracts, and civil law (and socialist) countries on
regulation (and state ownership).3
As argued by Glaeser and Shleifer [2002], there were
efficiency reasons for the choice of different legal systems in mother countries. However, since
most countries in the world received their legal structures involuntarily, their approach to social
control of business may be dictated by the history of transplantation rather than indigenous
choice.
Legal theory may be consistent with efficiency when one recognizes enforcement costs.
Suppose that a country inherits its broad legal tradition from its conquerors or colonizers. When
it does so, its basic laws, the institutions for enforcing the laws, and human capital of the law
enforcers, are all shaped by that legal tradition. Suppose that now a country decides to regulate a
3. Legal theories have been tested in other areas. Compared to civil law and particularly French civil
law countries, common law countries have better legal protection of shareholders and creditors [La Porta et al.
1997, 1998], lighter regulation of entry [Djankov et al. 2002], less formalized legal procedures for resolving
disputes [Djankov et al. 2003b], and securities laws more focused on private contracting than regulation [La Porta et
al. 2003a].
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 9/459
previously unregulated activity, such as work. Even if it does not wish to borrow the regulations
themselves from anywhere in the world, the marginal cost of adopting an approach similar to
that of the mother country is lower than starting from scratch, since both people and rules are
shared across regulatory activities [Mulligan and Shleifer 2003, 2005]. It might then be
efficient to adopt the same regulatory approach to the new area of regulation as is used
elsewhere. In this way, path dependence in the legal and regulatory styles emerges as an
efficient adaptation to the previously transplanted legal infrastructure.
The legal theory predicts that patterns of regulation of labor markets should follow the
general styles of social control utilized by each legal system more generally. It implies that civil
and socialist law countries would regulate labor markets more extensively than do common law
countries, which preserve the freedom of contract to a greater extent [Deakin 2001]. The legal
theory also predicts that common law countries should have a less generous social security
system, because they are more likely to rely on markets to provide insurance. Finally, the legal
theory predicts that patterns of regulation of different activities are correlated across countries.
Legal theories have been challenged by advocates of political power theories, such as
Roe [2000] and Pagano and Volpin [2001], who argue that at least in Western Europe, the civil
law tradition has often coincided with the political pressure to regulate, usually coming from the
left. By combining extensive data on political orientation and legal origins for a sample of 85
countries, we attempt to distinguish the pure political power from the pure legal theory.
III. Measures of Labor Regulation
We constructed a new data set that captures different aspects of the regulation of labor
markets in 85 countries. Our measures of labor regulation deal with three broad areas: (i)
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 10/4510
employment laws; (ii) collective relations laws; and (iii) social security laws. In addition, we
assembled some data on civil rights laws in different countries. We describe these data and
summarize the results in footnotes, but do not treat this area of law as systematically as the
others because there is extensive disagreement among the legal scholars as to what constitutes
civil rights. For each of the three areas of law, we examine a range of formal legal statutes
governing labor markets. We then construct sub-indices summarizing different dimensions of
such protection, and finally aggregate these sub-indices into indices. We construct all measures
so that higher values correspond to more extensive legal protection of workers.
As in our previous work, we measure formal legal rules. There are two concerns with
this approach. First, it has been argued that the quality of enforcement of rules varies
tremendously across countries, and therefore formal rules themselves provide little information
for what happens “on the ground” or outcomes. We cannot measure enforcement directly.
However, here as elsewhere, we can roughly control for enforcement quality. In addition,
despite the broad-brush criticism that formal rules do not matter, we show below that here, as
elsewhere, formal rules matter a lot [see La Porta et al. 1997, 1998, 2003, Djankov et al. 2002,
2003b].
Second, it has been argued that the focus on formal rules is misleading because, formally
distinct legal systems can and do achieve the same functional outcome, only through different
means. In the extreme form, the argument holds that in the French civil law tradition, the
practice is just to “write it down,” leading to greater measured formalism and interventionism. In
the present context, this argument would hold that the greater protection of workers in civil law
countries that we might identify is fictitious -- the common law countries regulate just as much
through court decisions which are never “written down” in statutes.4
For example, Autor [2003]
4. Bertola, Boeri, and Cazes [2000] examine the enforcement of employment protection by courts in a
few rich economies, and find that courts in the U.S. and Canada (common law countries) are less likely to rule for
workers than courts in Spain and France (French civil law countries). This bit of data suggests that court
enforcement, if anything, widens the differences between the French civil law and the common law that we
document below.
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 11/4511
and Krueger [1991] describe how common law courts in the U.S. have systematically deviated
from the employment at will doctrine even absent a statutory basis for such deviations.
To us, this critique is not convincing. First, virtually all of labor law is statutory, even in
common law countries, and deviations from statutes are an exception not the rule. Second, and
more importantly, we construct several of our indices, such as the cost of raising working hours
and the cost of firing workers, to reflect actual economic costs and not just statutory language.
For these variables, the distinction between what is written down and what it actually costs to do
something is minimized. At least with some key variables, then, we are measuring the
economic costs of worker protection -- functional differences -- and not pure formalism.
To codify our measures of worker protection, we used a range of sources. Table 1
presents brief definitions and sources of the variables used in the paper. The unpublished
appendix, available at http://iicg.som.yale.edu//, describes all data sources and full details of
variable construction (including civil rights5). To ensure comparability and consistency across
countries, we consider a “standardized” male worker and a “standardized” employer.6
III.A. Employment Laws
5. Civil rights laws seek to stop employment discrimination against vulnerable groups. Our index
reflects five such mandates: prohibition of discrimination on the basis of a) race or b) gender, c) the statutory
duration of paid maternity leave, d) minimum age of employment of children, and e) the existence of a statutory or
broadly applied minimum wage determined by law or mandatory collective agreements. The ostensible logic behind
the last variable is that the minimum wage protects disadvantaged persons against exploitation by those with more
power.
6. The standardized male worker has the following characteristics: (i) he is a non-executive full-time
employee who has been working in the same firm for 20 years; (ii) his salary plus benefits equal the country's GNP
per worker during the entire period of employment; (iii) he has a non-working wife and two children, and the family
has always resided in the country’s most populous city; (iv) he is a lawful citizen who belongs to the same race and
religion as the majority of the country’s population; (v) he is not a member of the labor union (unless membership is
mandatory); and (vi) he retires at the age defined by the country's laws. We also assume a “standardized” employer
with the following characteristics: (i) it is a manufacturing company wholly owned by nationals; (ii) its legal
domicile and its main place of business is the country’s most populous city; (iii) it has 250 workers; and (iv) it
abides by every law and regulation, but does not grant workers more prerogatives than are legally mandated.
Whenever both a standard duration or payment and a possible extended period of time or payment is provided by
law, we choose the standard one. These assumptions ensure comparability across countries; but they are not critical
for the results of the paper as variations in the overall level of labor protection are by far greater across countries
than across industries within a country. We collected information for a worker who has been employed for 3 years
and the results do not change materially.
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 12/4512
Employment laws regulate the individual employment relation, including the alternatives
to the standard employment contract, the flexibility of working conditions, and the termination
of employment. To capture all of these aspects, we calculate 4 sub-indexes: (i) alternative
employment contracts; (ii) cost of increasing hours worked; (iii) cost of firing workers; and (iv)
dismissal procedures. Our index of employment laws, more so than other indices, reflects the
incremental cost to the employer of deviating from a hypothetical rigid contract, in which the
conditions of a job are specified and a worker cannot be fired. This index is thus an economic
measure of protection of (employed) workers, and not just a reflection of legal formalism.
An employer can reduce his costs by hiring part time labor or through temporary
contracts if such practices reduce benefits or termination costs. The first sub-index captures the
strictness of protection against such alternative employment contracts. We measure whether part-
time workers are exempt from mandatory benefits of full-time workers and whether it is easier or
less costly to terminate part-time workers than full time workers. We also measure whether
fixed-term contracts are only allowed for fixed-term tasks and their maximum allowed duration.
The second sub-index measures the cost of increasing working hours. We assume that
our hypothetical firm in each country has each employee working at 1758 hours per year initially
(Denmark’s maximum considering all regulations before overtime), and it wants to increase
these numbers by 660 hours per year per worker due to increased demand (which would bring it
to 2418 hours per year per worker, Kenya’s legal maximum before overtime). We assume that
the firm in each country meets the increased need for labor by first asking its workers to work up
to the country’s legal maximum, then asking them to work overtime at the statutory wage
premiums. If neither proves sufficient, we assume that the firm must instead hire another
complete duplicate set of workers each working the initial 1758 hours (i.e., workers are
complements and each job must be filled with an extra worker to meet the increased demand).
Under these assumptions, we can calculate the cost of accommodating increased demand relative
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 13/4513
to the firm’s previous wage bill, a measure of how strictly employment laws protect workers
from being “forced” to work more.
The third sub-index captures the economic cost of firing workers. We construct a
scenario where our standardized firm with 250 workers fires 50 of them, 25 for redundancy and
25 without cause. The cost of firing workers is computed as the equivalent in pay of the sum of
the notice period, severance payment and any other mandatory penalty directly related to the
dismissal of the worker.7
Because many rules govern when a redundancy or no cause dismissal is
allowed, we make assumptions to make the scenario comparable across countries.8
If the laws of
a country do not allow the firm to fire a worker, the cost is set equal to his full year’s salary.
The fourth sub-index summarizes the restrictions on employers for firing workers;
whether individually or collectively. These may include notifications, approvals, mandatory
relocation or retraining, and priority rules for re-employment. Their effect is to raise the costs
of dismissal of existing workers beyond those already captured in the previous sub-index.
III.B. Collective Relations Laws
Collective relations laws seek to protect workers from employers through collective
action. They govern the balance of power between labor unions and employers and associations
7. For the cost of firing workers sub-index, we report results for an employee with 3 years of seniority.
We also calculated the relevant data for a worker with 2 and 20 years of seniority with no significant change in
results.
8. In particular, we assume that: (i) There is no discrimination and all procedures regarding notice
periods and social conditions for firing are followed (this includes last-in first-out rules as well as seniority and
“social need” criteria); (ii) The negative demand shock puts the firm in “manifest un-profitability” and therefore
redundancy dismissal is allowed whenever the law permits it for economic reason less stringent than outright
bankruptcy; (iii) Whenever permission from a third party (courts, government regulators, worker councils, or labor
unions) is required prior to dismissing a worker, third party consents to the dismissal; (iv) If permission from a third
party is required for a dismissal without cause, the third party does not allow it; (v) If dismissal without cause is not
allowed but the law establishes a clearly defined penalty for firing the worker (which does not include mandatory
reinstatement), the employer fires the employee and pays the fine.
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 14/4514
of employers.9
We deal with two sub-areas of these laws: (i) the power granted by the law to
labor unions and (ii) the laws governing collective disputes.
The sub-index of labor union power measures the power of labor unions over working
conditions. Many countries protect by law the right to unionization, the right to collective
bargaining, and the obligation of employers to engage in it. In some countries collective
agreements are extended to third parties as a matter of public policy at the national or sectoral
levels, whereas in others they only extend to non-signatory workers at the plant level, or only
bind the parties to the agreement. Laws in some countries mandate closed shops, and even give
unions the right to appoint some directors of firms. Finally, many countries require by law the
creation of workers councils to look after the best interests of employees.
The second sub-index measures protection of employees engaged in collective disputes.
Some countries enshrine the right of workers to engage in collective action in their constitutions,
and allow wildcat strikes (not authorized by the labor union), political strikes (to protest
government policy on non work-related issues), and sympathy strikes (to support the claims of
workers other than the striking workers). Others do not. Procedural restrictions on the right to
strike may include majority voting, advance notice requirements, prohibitions on strikes while a
collective agreement is in force, and the obligation to go through conciliation procedures before
the strike may take place. Employer defenses may include bans on lock-outs and on employers’
retribution against strikers, such as the termination of employment of striking workers and the
hiring of replacement labor during a lawful strike. Finally, in many countries, one (normally the
employer) or both of the parties may be subject to arbitration against their will.
III.C. Social Security Laws
The bulk of social security expenditure across countries addresses old-age pensions,
9. Some provisions aim to protect workers from other workers. For instance, “right-to-work” laws in the
U.S. protect workers from unions by prohibiting the exclusive hiring of union labor. Such cases are rare and the
bulk of collective relations provisions protect workers from employers.
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 15/4515
sickness and healthcare coverage, and unemployment. Following the design of the de-
commodification index of Esping-Andersen10
, our variables cover the risks of: (i) old age,
disability, and death; (ii) sickness and health; and (iii) unemployment. For each, we code four
variables to measure the generosity of the social security system.
The construction of each sub-index is slightly different, but all capture the generosity of
benefits by measuring the percentage of the net previous salary covered by net benefits. This
measure approximates the living standard a worker would enjoy considering the effects of the
tax structure and the duration for which benefits are received.11
A second driver of generosity is
the cost borne by the worker for the privilege of social security coverage. We approximate this
by measuring the required months of contribution or of covered employment required by law to
qualify for a standard pension or to enjoy unemployment and sickness benefits as well as the
percentage of the worker's monthly salary deducted by law to cover these. Finally, we consider
the length of the waiting period before receiving benefits.
III.D. Aggregation
For each of our three areas of law, we construct an aggregate index by averaging the sub-
indices for the particular area. This is not the only possible aggregation procedure, but it is
transparent. Table II presents the correlations between the various sub-indices and indices of
labor regulation. The table shows for example that the four sub-indices of the employment laws
index are highly correlated with each other, as are the two sub-indices of the collective relations
law index, and the three sub-indices of the social securities law index. The correlations between
employment and collective relations indices and sub-indices are high and significant as well,

his index for 18 developed countries. This information is not available for a large sample of countries, so we present
the un-weighted data. The correlation between the Esping-Andersen index and our index of social security laws for
the 18 countries in his sample is 0.38.

inconsistent with the notion of substitution between different kinds of regulation.
III.E. Independent Variables
We assemble data on a number of potential determinants of labor regulations, as well as
some labor market outcomes. We measure development using the (logarithm of) per capita
income in 1997 (the year the regulations are measured), and the average years of schooling of
the population over 25 years of age from Barro and Lee [2000].
To measure politics, we expand back to 1928 the World Bank data recording the fraction
of years between 1975 and 1995 that each country’s chief executive and/or the largest party in
the legislature was rightist, leftist, or centrist. We present results for the fraction of years during
1928-1995 and 1975-1995 when the chief executive AND the legislature were of left or centrist
orientation (these variables yield the strongest results for the political theories). We use union
density to proxy for the influence of labor interest groups. To measure political constraints, we
take average “autocracy” between 1950 and 1990 from Alvarez et al. [2000], and the 1975-1995
averages of proportional representation and divided government from Beck et al. [2001].12
To test legal theories, we use legal origin of commercial laws from La Porta et al. [1999],
which classifies close to 200 countries. Labor market outcomes include the size of the unofficial
economy, labor force participation, unemployment including that of the young, and a crude
measure of relative wages of protected and unprotected workers.
IV. A Look at the Data.
12. We have gathered additional variables that measure political orientation as well as political and
economic constraints. Additional measures of political orientation include: the fraction of years when the chief
executive was of left and centrist orientation; the fraction of years when the legislature was of left or centrist
political orientation; and the percentage of the labor force covered by collective agreements. Alternative measures
of political constraints are the effectiveness of the legislature and constraints of the executive. We also used
alternative measures of proportional representation and divided government from various sources including
plurality rules in the legislature chambers, and the sum of the square of the total share of the congress controlled by
each party. Finally, our measures for economic constraints are: actual trade openness in 1985; geographic openness;
and factor accumulation openness from Frankel and Romer [1999].

http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 17/4517
A comparison of New Zealand and Portugal, two countries of roughly similar income
level can serve to illustrate our indices. In the area of employment laws, neither country exempts
part time workers from mandatory benefits of full time workers, and neither makes it easier or
less costly to terminate them. Fixed term contracts can be entered in New Zealand for any
reason and there is no maximum duration provided by the law. In Portugal, such contracts are
allowed for a maximum of three years, are granted for specific situations (such as substitution for
another worker or seasonal activity) and are therefore temporary in nature. The alternative
employment sub-index for New Zealand is 0.50 while for Portugal it is 0.91.
The Portuguese Constitution regulates working times and leaves, remuneration, and
working conditions, matters that in New Zealand are normally regulated by collective bargaining
or left to the individual employment contract. The premium for overtime work in Portugal is 50
percent for the first 6 hours per week and 75 percent for every hour thereafter, there are 24 days
of paid annual leave and there is a cap of 200 hours of overtime per year. New Zealand mandates
no premium for overtime work, has no quantitative restrictions on night work, and only grants 15
days of paid leave. The result of this is that the cost of increasing working hours in Portugal is
equal to the maximum in our sample (1.00) while the cost in New Zealand is the lowest in our
sample (0.00).
In New Zealand, notice period and severance pay are not regulated by statute, while in
Portugal the minimum notice period and severance period that may be paid are strictly regulated;
for example, a worker with three years seniority fired for redundancy in Portugal is entitled to 1
month of notice and 3 months of severance pay. Dismissal without cause is allowed in New
Zealand, but constitutionally forbidden in Portugal. These factors explain why New Zealand has
the lowest cost of dismissal in our sample (0.00), while Portugal has one of the highest (0.61).
In New Zealand, a reasonable advance notice is generally considered a fair reason for
termination for redundancy. Portugal, on the other hand, has a public policy list of fair grounds
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 18/4518
for termination and stringent procedural limitations on dismissal, such as mandatory notification
of the government, permission in the case of collective dismissal, and priority rules for re-
employment of redundant workers. These differences are reflected in the dismissal procedures
sub-index, where New Zealand scores a 0.14 and Portugal a much higher 0.71.
These differences add up to the employment laws index of 0.16 for New Zealand (one of
the lowest in the world), and 0.81 for Portugal (one of the highest).
In collective relations laws, the Portuguese Constitution guarantees the rights to form
trade unions and to engage in collective bargaining. Employers have a legal duty to bargain with
unions, collective agreements are extended to third parties by law, and workers councils
allowing workers to participate in management are mandatory. In New Zealand, these issues are
not regulated by law. For example, once a bargaining agent has established its authority to
represent an employee, the employer must recognize his authority, but there is no obligation
upon the employer to negotiate with this agent. In New Zealand, as in Portugal, the law does
not allow closed shops. These differences explain why the sub-index of labor union power for
New Zealand is 0, the lowest possible, while Portugal’s is 0.71, the highest in our sample.
Regarding collective disputes, the two countries are similar. The right to strike is
protected in both countries, but while it is a mere freedom in New Zealand, it is a constitutional
right in Portugal. Employer lockouts are allowed in New Zealand, but not in Portugal. New
Zealand does not mandate a waiting period or notification before strikes can occur, while
Portugal requires employers to be notified before the strike. In both countries, employers are not
allowed to fire or replace striking workers, there is no mandatory conciliation procedure before a
strike, and compulsory third-party arbitration during a labor dispute is not mandatory. The
overall collective disputes sub-index is 0.58 in Portugal and 0.50 in New Zealand; the overall
collective relations laws index is 0.65 for Portugal compared to 0.25 for New Zealand.
Although social security is regulated by the Constitution in Portugal but not in New
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 19/4519
Zealand, the two countries have similar – and generous – systems. In the case of old age,
disability and death insurance, workers in New Zealand are not only obliged to contribute less to
their retirement, but can also expect to enjoy their benefits for 13.4 years while those in Portugal
only expect 10.5 years. The percentage of the previous net wage covered by net benefits is 76
percent in New Zealand and only 58 percent in Portugal. For the overall old age, disability and
death benefits sub-index New Zealand scores a 0.84, and Portugal only 0.60.
Sickness and health benefits in Portugal require 6 months of contributions before benefits
can be claimed, 3.17 percent of the workers monthly pay is deducted to pay for insurance, and
there is a waiting period of 3 days between the time the employee falls ill and payments begin.
New Zealand has no minimum contribution conditions, no waiting period, and does not deduct
pay from workers to cover for insurance. Net benefits in Portugal cover approximately 65
percent of the net previous wage, while benefits in New Zealand are income tested and our
model worker falls above the threshold. These differences roughly cancel each other out: New
Zealand has a sickness and health benefits sub-index of 0.75, and Portugal of 0.70.
For unemployment benefits, New Zealand has no minimum contribution period, while
Portugal mandates 18 months. However Portugal has no waiting period from the time an
employee is fired and when he can claim benefits, while a worker in New Zealand must wait for
70 days. The benefits received are also more generous in Portugal: the net benefit is 77 percent
of net previous wages, while only 25 percent in New Zealand. The results of this are that the sub-
index of unemployment benefits is 0.56 for New Zealand and a much higher 0.90 for Portugal.
The three measures of social security translate into a slightly higher score in the social
security laws index of 0.74 for Portugal than 0.72 given to New Zealand.
Table III presents, for each country, the indices of employment, collective relations, and
social security laws, as well as the logarithm of GDP per capita in 1997, the fraction of years
during 1928-1995 when the chief executive and the legislature were of left or centrist
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 20/4520
orientation, and the legal origin. The table also presents the means and medians of the data
across income groups, degrees of leftist political orientation, and legal origins. At first glance,
the data suggest that richer countries have more generous social security systems than poorer
ones but otherwise similarly protective labor laws, that countries with more left wing
governments have more protective laws than those with less leftist ones, and that common law
countries protect labor less than do those from the four civil law traditions. Below we examine
these data systematically.
V. Testing the Theories
In Table IV, we examine the relationship between the protection of workers and two of
its potential determinants: income per capita and legal origin. There is no evidence that
employment laws or collective relations laws vary with the level of economic development. This
result is inconsistent with the implication of the efficiency hypothesis that rich countries should
regulate less because they have fewer market failures. In contrast, there is clear evidence that
richer countries have more generous social security systems, both as measured by the aggregate
index and for old age, health, and unemployment benefits separately.
The results in Table IV also show that legal origin matters for several areas of labor law.
In employment laws, all categories of civil law countries have higher values of the index than do
the common law countries, and the differences are quantitatively large for French, socialist, and
Scandinavian legal origins. The explanatory power of legal origins is high: the R 2 of the
regression is 44 percent. Differences among legal origins are also large for collective relations
laws, with common law countries being less protective of workers than civil law countries. The
R 2 here is 31 percent. With social security laws, the picture is more complex. Socialist,
Scandinavian, and French legal origin countries, but not German legal origin countries, have
more generous systems than do the common law countries. Since income is so important for
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 21/4521
social security laws, the R 2 of this regression rises to a somewhat unbelievable 64 percent. In
short, legal traditions are a strikingly important determinant of various aspects of statutory
worker protection, with French and socialist legal origin countries being most interventionist,
consistent with the evidence on regulation of other aspects of economic life [La Porta et al. 1999,
Djankov et al. 2002].
Panel D of Table IV focuses on Roe’s [2000] hypothesis that civil law is a proxy for
social democracy by re-running the regressions for the three aggregate law indices using the sub-
sample of non-democracies during 1950-1995. Even in non-democracies, legal origin remains
an important determinant of employment, collective relations, and social security laws,
inconsistent with the view that it proxies for social democracy. This result is robust to a variety
of definitions of non-democracy we have tried.
Table V examines the effect of politics on labor laws, holding per capita income constant.
Countries with longer histories of leftist or centrist governments between 1928 and 1995, as well
as between 1975 and 1995, have heavier regulation of labor markets, as measured by
employment, collective relations, and social security laws (5 out of 6 coefficients are statistically
significant).13
Higher union density is also associated with stronger worker protection. These
results support political theories, which hold that worker protection comes from their political
power, although the explanatory power of the political variables is sharply lower than that of
legal origins, as reflected in the lower R 2 of these regressions.14
In addition Table V presents mixed evidence on the importance of constraints on
13. These results also hold mostly, although at lower level of statistical significance, if we use the pure
leftist government variables (rather than the combination of leftist and centrist governments), or if we use the
executive or the legislative branch separately.
14. We ran regressions with more variables that are related to the political view of regulation. The
results show that the Gini coefficient has a significant negative effect on all but collective relations laws. Measures
of ethnic, linguistic, and religious heterogeneity from Alesina et al. [2003] also have a negative effect, inconsistent
with the theory that labor laws are efficiently more protective of workers when social divisions are greater. Tax
efficiency affects negatively collective relations laws only. Finally, public old age pensions/GNP (1960-1995) has
significant positive effects on employment and social security laws. Once we control for legal origin, however, all
these go away, except the effect of public pensions on employment and collective relations laws at the 10 percent
significance level.
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 22/4522
government. Countries with proportional representation have more protective employment and
collective relations laws, suggesting that constraints on the executive lead to more protection.
But the result does not hold for other variables. These results offer mixed support for the view
that constraints on government lead to less intervention in markets. However, they do provide
some support for the Alesina-Glaeser [2004] theory that proportional representation as a form of
democracy is a reflection of labor power, as are the laws protecting labor.15
Table VI presents the results of a horse race between legal origins and politics. We
exclude socialist legal origin countries from the sample because of extremely high correlations
between leftist variables and socialist origin, but all the results hold on a larger sample as well.
Legal origin wins out and accounts for the bulk of the R
2
. In 6 out of 9 regressions, the proxies
for politics lose their consistent influence on the regulation of labor. In contrast, the difference
between common law and French legal origin countries is always statistically significant. The
average French legal origin country has employment and collective relations laws scores 50 to
100 percent higher than the average common law country. German and Scandinavian legal
origin countries continue to be more protective than common law countries, although the results
are not quite as consistent as in Table V for Scandinavian legal origin. We conclude that the
effects of legal origin on the regulation of labor are larger and different from those of politics.16
This evidence does not suggest that politics does not matter, but it is inconsistent with the
extreme hypothesis that law is just a proxy for social democracy. The importance of legal origin
– and the unimportance of per capita income – is also difficult to reconcile with the efficiency
theory of regulation of labor, except for the version that sees the efficiency of regulatory
15. Other measures of political constraints impact labor regulation without legal origin control, but not
once we control for legal origin. Economic constraints on government, measured by proxies for trade openness
from Frankel and Romer [1999], have a weak impact on employment laws and collective relations laws, but do
affect social security laws when controlling for legal origin.
16. We also considered the effects of the religious composition of the population in 1900 and in 1980--
our proxy for culture -- on contemporary labor laws. There are no statistically significant effects of religious
variables measured in 1900. For 1980 measures, we find that catholic countries have more protective collective
relations and social security laws, but the significance is small and typically does not survive a control for legal
origin.
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 23/4523
schemes stemming largely from their compatibility with the country’s broader legal
framework.17
VI. Regulation in Different Domains
One of the strongest implications of the legal theory is that societies have regulatory
styles shaped in part by their legal systems, and that therefore societies that regulate one activity
are also expected to regulate others, which might be totally unrelated. We have already shown in
earlier work that French civil law countries regulate entry of new firms, dispute resolution in
courts, and other activities more heavily than do common law countries [La Porta et al. 1999,
Djankov et al. 2002, 2003b]. The findings of this paper are broadly consistent with this research.
Table VII presents the correlations between our measures of regulation of labor and the
measures of regulation of entry from Djankov et al. [2002] and of legal formalism from Djankov
et al. [2003b]. The data show that all these aspects of regulation go together, even though the
methodologies of data collection differ tremendously across the three studies. The correlation
between the employment laws index and the judicial formalism index is 0.33 for one case, and
0.41 for the other. The correlation between the employment laws index and the logarithm of the
number of steps required to start a business is 0.34. These correlations fall by about 0.05 if we
exclude socialist countries, but remain highly statistically significant. The numbers are even
higher for the collective relations laws, although generosity of social security systems is
negatively correlated with entry regulation (because income matters for both in opposite
directions). Regulatory style is pervasive across activities -- consistent with the legal theory.
VII. Outcomes
Finally, we consider some of the consequences of the regulation of labor. This is of
17. Our index of civil rights laws, described in footnote 6, does not depend on income per capita, is
higher in socialist countries but does not otherwise depend on legal origins. It is strongly correlated with leftist
government measures, even controlling for legal origin.
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 24/4524
interest for two reasons. First, efficiency theories predict that heavier regulation of labor markets
should be associated with better, and certainly not worse, labor market outcomes. This
prediction has been contradicted by a variety of empirical studies from Lazear [1990] to Besley
and Burgess [2003], and here we confirm their findings. Second, if the regulation of labor is
damaging at least to some workers, then who benefits from it? Put differently, is there political
support for the heavier regulation of labor, or does legal origin simply provide a politically
unsupported “technology” for the social control of labor markets?
We look at several potential consequences of labor regulation. These include the size of
and the employment in the unofficial economy, male and female participation in the labor force,
and unemployment computed separately for everyone, and for male and female workers aged 20-
24. In addition, as a crude measure of relative wages of protected and unprotected workers, we
consider the average wage of machine operators relative to that of clerks and workers in craft
and related trades. All of these variables have measurement problems, particularly for the
developing countries, where some employment is informal and not recorded in official statistics.
Still, by looking at the various dimensions of the data, we hope to get a general picture.
Table VIII presents the results. In all specifications, we control for average years of
schooling (which is less likely to be itself caused by regulations than income per capita) as a
proxy for the quality of law enforcement.18
The strength of the results varies across
specifications, but in general they show no benefits, and some costs, of labor regulation. There is
some evidence that more protective collective relations laws (but not others) are associated with
a larger unofficial economy, that more protective employment, collective relations, and social
security laws lead to lower male (but not female) participation in the labor force, and that more
protective employment laws lead to higher unemployment, especially of the young. Finally,
there is some evidence that more generous social security systems are associated with higher
18. As alternative enforcement measures, we used the length of court proceedings in collecting a
bounced check and evicting a tenant from Djankov et al [2003b], with no change in results.
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 25/4525
relative wages of privileged workers. The evidence on the unemployment of the young is most
consistent with the political view that the privileged and older incumbents support more stringent
labor laws, a finding broadly consistent with other research [Blanchflower and Freeman 2000].
As an additional way to examine enforcement, we divide the sample into countries with
per capita income above and below the median, and replicate the analysis in Table VIII. The
results hold among the richer, but generally not the poorer, countries. This evidence is
consistent with the view that labor laws have adverse consequences in countries where they are
more likely to be enforced, namely the richer ones. This evidence sheds further doubt on the
efficiency theory, since it confirms the damage from regulation precisely when the laws have a
bigger bite.
We also re-estimated the regressions in Table VIII with instrumental variables, using
legal origins (either just the common law dummy or all of them) as instruments . The results for
male labor force participation, and the unemployment rates, particularly of the young, remain
statistically significant in most cases, and many coefficients rise in magnitude. The results on
the relative wages of privileged and less privileged workers become stronger.
All of this evidence does not provide much support for the efficiency theory, namely that
labor regulations cure market failures, although of course it is possible that the adverse outcomes
we measure are unavoidable to alleviate capitalist abuse of workers. The results are consistent
with the view that legal origins shape regulatory styles, and that such dependence has adverse
consequences for at least some measures of efficiency.
VIII. Conclusion
There are three broad theories of government regulation of labor. Efficiency theories
hold that regulations adjust to efficiently address the problems of market failure. Political
theories contend that regulations are used by political leaders to benefit themselves and their
8/3/2019 Db Methodology Regulation of Labor
http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 26/4526
allies. Legal theories hold that the patterns of regulation are shaped by each country’s legal
tradition, which is to a significant extent determined by transplantation of a few legal systems.
We examined the regulation of labor markets in 85 countries through the lens of these theories.
As we indicated, the efficiency theory is difficult to reject, but we do not find much
support for conventional versions. In particular, we find that heavier regulation of labor has
adverse consequences for labor force participation and unemployment, especially of the young.
There is some support for the view that countries with a longer history of leftist governments
have more extensive regulation of labor, consistent with the political theory. There is, finally,
strong evidence that the origin of a country’s laws is an important determinant of its regulatory
approach, in labor as well as in other markets. Moreover, legal origin does not appear to be a
proxy for social democracy -- its explanatory power is both independent and significantly larger.
This evidence is broadly consistent with the legal theory, according to which patterns of
regulation across countries are shaped largely by transplanted legal structures.
These results do not mean that efficiency forces in regulation are unimportant, and indeed
our focus on a large sample of developing countries, as opposed to just the rich ones where the
law evolves more quickly, predisposes our findings against the efficiency hypothesis. These
findings also do not mean that politics is unimportant, and indeed we find evidence that it
matters. Still, the main factor explaining labor laws in our data is legal origin.
This evidence echoes our earlier results on the regulation of entry and on the formalism
of judicial procedures. Those findings also showed that countries from different legal origins
rely on different institutional technologies for social control of business. A key result in the
present paper is the high correlation among our measures of regulation of different activities
across countries: countries that regulate entry also regulate labor markets and judicial
proceedings. The bottom line of this research is the centrality of institutional transplantation:
countries have regulatory styles that are pervasive across activities and shaped by the origin of
8/3/2019 Db Methodology Regulation of Labor

their laws.

TABLE I
The variables
This table presents brief definitions of the variables used in the paper. For a full description of all variables and the data refer to the on-l
appendix posted at <http://iicg.som.yale.edu//>. Unless otherwise specified, the sources for the variables are the laws of each country. W
also relied on secondary sources to confirm our data, including the International Encyclopedia for Labor Law and Industrial Relations,
International Handbook on Contracts of Employment, the ILO’s Conditions of Work Digest (1994, 1995), and the U.S. Social Secur
Administration’s Social Security Programs Throughout the World. Unless otherwise specified, higher values indicate higher work
protection. All dummy variables are equal to 1 or zero. All normalized variables lie between 0 and 1, where 0 (1) is the minim
(maximum) actual value in our sample.
Variable Description
Employment laws
Alternative employment
contracts
Measures the existence and cost of alternatives to the standard employment contract, computed as the aver
of: (1) a dummy variable equal to one if part-time workers enjoy the mandatory benefits of full-time worke
(2) a dummy variable equal to one if terminating part-time workers is at least as costly as terminating full ti
workers; (3) a dummy variable equal to one if fixed-term contracts are only allowed for fixed-term tasks;
(4) the normalized maximum duration of fixed-term contracts.
Cost of increasing hours
worked
Measures the cost of increasing the number of hours worked. We start by calculating the maximum numbe
“normal” hours of work per year in each country (excluding overtime, vacations, holidays, etc.). Norm
hours range from 1,758 in Denmark to 2,418 in Kenya. Then we assume that firms need to increase the ho
worked by their employees from 1,758 to 2,418 hours during one year. A firm first increases the number
hours worked until it reaches the country’s maximum normal hours of work, and then uses overtime
existing employees are not allowed to increase the hours worked to 2,418 hours in a year, perhaps beca
overtime is capped, we assume the firm doubles its workforce and each worker is paid 1,758 hours, doubl
the wage bill of the firm. The cost of increasing hours worked is computed as the ratio of the final wage bil
the initial one.
Cost of firing workers Measures the cost of firing 20 percent of the firm’s workers (10% are fired for redundancy and 10% with
cause). The cost of firing a worker is calculated as the sum of the notice period, severance pay, and
mandatory penalties established by law or mandatory collective agreements for a worker with three years
tenure with the firm. If dismissal is illegal, we set the cost of firing equal to the annual wage. The new w
bill incorporates the normal wage of the remaining workers and the cost of firing workers. The cost of fir
workers is computed as the ratio of the new wage bill to the old one.
Dismissal procedures Measures worker protection granted by law or mandatory collective agreements against dismissal. It is
average of the following seven dummy variables which equal one: (1) if the employer must notify a third pa before dismissing more than one worker; (2) if the employer needs the approval of a third party prior
dismissing more than one worker; (3) if the employer must notify a third party before dismissing o
redundant worker; (4) if the employer needs the approval of a third party to dismiss one redundant worker;
if the employer must provide relocation or retraining alternatives for redundant employees prior to dismis
(6) if there are priority rules applying to dismissal or lay-offs; and (7) if there are priority rules applying to
employment .
Employment laws index Measures the protection of labor and employment laws as the average of: (1) Alternative employm
contracts; (2) Cost of increasing hours worked; (3) Cost of firing workers; and (4) Dismissal procedures.
Collective relations laws
Labor union power Measures the statutory protection and power of unions as the average of the following seven dummy variab
which equal one: (1) if employees have the right to unionize; (2) if employees have the right to collect
bargaining; (3) if employees have the legal duty to bargain with unions; (4) if collective contracts are exten
to third parties by law; (5) if the law allows closed shops; (6) if workers, or unions, or both have a right
appoint members to the Boards of Directors; and (7) if workers’ councils are mandated by law.
Collective disputes Measures the protection of workers during collective disputes as the average of the following eight dumm
variables which equal one: (1) if employer lockouts are illegal; (2) if workers have the right to indust
action; (3) if wildcat, political and sympathy/solidarity/secondary strikes are legal; (4) if there is no mandat
waiting period or notification requirement before strikes can occur; (5) if striking is legal even if there i
collective agreement in force; (6) if laws do not mandate conciliation procedures before a strike; (7) if th
party arbitration during a labor dispute is mandated by law; and (8) if it is illegal to fire or replace strik
workers.
Collective relations laws
index
Measures the protection of collective relations laws as the average of: (1) Labor union power; and
Collective disputes.

http://slidepdf.com/reader/full/db-methodology-regulation-of-labor 36/4536
Variable Description
Social security laws
Old age, disability and
death benefits
Measures the level of old age, disability and death benefits as the average of the following four normaliz
variables: (1) the difference between retirement age and life expectancy at birth; (2) the number of months
contributions or employment required for normal retirement by law; (3) the percentage of the work
monthly salary deducted by law to cover old-age, disability, and death benefits; and (4) the percentage of
net pre-retirement salary covered by the net old-age cash-benefit pension.
Sickness and health benefits Measures the level of sickness and health benefit as the average of the following four normalized variables:
the number of months of contributions or employment required to qualify for sickness benefits by law; (2)
percentage of the worker’s monthly salary deducted by law to cover sickness and health benefits; (3)
waiting period for sickness benefits; and (4) the percentage of the net salary covered by the net sickness ca
benefit for a two-month sickness spell.
Unemployment benefits Measures the level of unemployment benefits as the average of the following four normalized variables:
the number of months of contributions or employment required to qualify for unemployment benefits by la
(2) the percentage of the worker's monthly salary deducted by law to cover unemployment benefits; (3)
waiting period for unemployment benefits; and (4) the percentage of the net salary covered by the
unemployment benefits in case of a one-year unemployment spell.
Social security laws index Measures social security benefits as the average of: (1) Old age, disability and death benefits; (2) Sickness
health benefits; and (3) Unemployment benefits.
Political variables
Chief executive and largest
party in congress have left
or center political
orientation
Measures the percentage of years between 1928 and 1995, and, alternatively, between 1975 and 1995, dur
which both the party of the chief executive and the largest party in congress had left or center orientation
the country was not independent in the initial year of the period, we use the independence year as the f
period. For countries that were part of a larger country in the initial year of the period and subsequently bro
up, we include in calculations the political orientation of the political parties in the mother country in the p
breakup period. In the case of military regimes, where political affiliations are unclear, we classify the regi
based on its policies. Source: uthors’ calculations based on: Political Handbook of the World, Euro

<http://laborsta.ilo.org >, and The World Bank [2001].
Autocracy This variable classifies regimes based on their degree of autocracy. This variable ranges from zero to tw
where higher values equal a higher degree of autocracy. Democracies are coded as 0, dictatorships wit
legislature are coded as one, and dictatorships without a legislature are coded as two. Transition years
coded as the regime that emerges afterwards. This variable is measured as the average from 1950 throu
1990. Source: Alvarez et al. [2000].
Proportional representation Equals one if legislators were elected based on the percentage of votes received by their party; equals z
otherwise. This variable is measured as the average from 1975 through 1995. Source: Beck et al. [2001].
Divided government This variable measures the probability that two randomly chosen deputies will belong to a different party i
given year. It is missing if there is no parliament or if there are no parties in the legislature; and zero if th
are no opposition party seats. This variable is measured as the average from 1975 through 1995. Source: B

Democracy A measure of the degree of democracy in a given country based on: (1) the competitiveness of politi
participation; (2) the openness and competitiveness of the chief executive recruitment; and (3) the constrai
on the chief executive. The variable ranges from zero to ten, where higher values represent a higher degree
institutionalized democracy. The starting period is either 1950 or the country’s independence date, whiche
is later. The variable is measured as the average from the initial period through 1995. For countries that
break-up nations, we include in the calculations the democracy score of the mother country in the pre-break
period. Source: Author’s calculations using the data in Jaggers and Marshall (2000).

Regulation of labor and legal origin
Ordinary least squares regressions of the cross section of countries. The dependent variables are: (1) the employment laws index and its
omponents (in Panel A); (2) the collective relations laws index and its components (in Panel B); and (3) the social security laws index
nd its components (in Panel C). In Panel D we repeat regressions for the three aggregate indices for countries classified as "non-
emocracies" during the period 1950-1995. Using democracy scores from Jaggers and Marshall (2000), we classify as non-democracies
ountries with the 1950-1995 average democracy score below 8. The 21 countries classified as democracies, and left out of the sample in
anel D are: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, India, Ireland, Israel, Italy, Jamaica, Japan,
Netherlands, New Zealand, Norway, Sweden, Switzerland, the United Kingdom and the United States. Robust standard errors are shown
n parentheses. All the variables are described in Table I and the data can be found in http://iicg.som.yale.edu/.
